[jboss-user] [JBoss Seam] - Re: Page Parameter validation - Bug in org.jboss.seam.naviga

[wschwendt]

It does not only look like a bug, it is a bug.

For page parameters, one can specify a JSF converter and a JSF validator.

[SeamReference -> 5.1.1.1.3. Conversion and Validation]

A JSF validator can be specified by way of a JSF validator id or alternatively a value expression.


If a value expression is used, it should refer to an object which implements interface javax.faces.validator.Validator, and thus  the method

javax.faces.validator.Validator.validate(FacesContext context,              UIComponent component,               Object value)              throws ValidatorException


With the current code  in org.jboss.seam.navigation.Pages.convertAndValidateStringValuesInPageContext(),    the problem is that Validator.validate() is called not with the converted object value, but rather with the unconverted (!) String value for the page parameter.
